Leaders signing to Tech Valley High

It doesn’t have a single student yet, but Tech Valley High School is claiming another milestone.

The educational and business leaders behind the push for a new math- and science-focused high school say they signed on four prominent area leaders to the cause. They haven’t said who they have, but will introduce them at 11 a.m. tomorrow at MapInfo Corp.’s headquarters in Rensselaer Technology Park in North Greenbush.

The school, first proposed in 2004, is slated to open next September with 30 freshman in space borrowed from MapInfo.

Ultimately, Tech Valley High expects to draw students from 48 school districts in seven counties.
